System Security

Caution: High Security Setting Recommended

We recommend always using the High security setting unless you have a specific and compelling need to allow one of the insecure capabilities.

We recommend the Maximum security setting only for those environments where the most stringent security protocols must be adhered to.

Enabling Maximum security is irreversible and has significant consequences (see The Consequences of Enabling Maximum Security Mode on page 55). Don’t choose this setting unless you know what you’re doing and are prepared for the consequences. Refer to the Polycom RealPresence DMA 7000 System Deployment Guide for Maximum Security Environments for additional important information about enabling this setting.

Note: Security Settings Must Match Across Superclusters

All clusters in a supercluster must have the same security settings. Before attempting to join a supercluster, make sure the cluster’s security settings match those of the other members of the supercluster. You can’t change a cluster’s security settings while it’s part of a supercluster.

Note: Maximum Security Mode Unsupported in Virtual Edition

The RealPresence DMA system, Virtual Edition, does not support Maximum Security Mode.

The following table describes the options in the Security Settings page.

Field	Description
Maximum security	An extremely high security mode suitable for use where very strict security
	requirements apply.
	Once this mode is enabled, it’s no longer possible to reduce the security level.
	See caution above.
High security	Recommended setting for normal operation.
Custom security	Lets you enable one or more of the unsecured methods of network access
	listed below it.
Allow Linux console access	Enables the Linux user root to log into the system using SSH. This direct
	Linux access isn’t needed for normal operation, routine maintenance, or even
	troubleshooting, all of which can be done through the administrative GUI.
	In extreme circumstances, this option might enable expert Polycom Global
	Services personnel to more fully understand the state of a troubled system or
	correct problems. Enable this option only when asked to do so by Polycom
	Global Services.
